Abstract
Un sistema para evitar la microsoldadura de un aro de piston instalado en una ranura circunferencial de un piston, en la que el aro por lo menos una superficie de acoplamiento con la ranura de piston, la cual está recubierta con resina termoendurecible, politetrafluoroetileno y disulfuro de molibdeno. Esta composicion proporciona lubricacion crítica durante el piston y el periodo de interposicion del aro del piston y evita la presion elevada localizada y áreas de alta temperatura las cuales promueven la microsoldadura.
